While using a screen reader to read PDFs, users can change the reading settings for the current document like reading order and mode.

1. Click Accessibility > Reading Option.
2. Choose the desired reading options and click Start.

Note: The preferences set here are only valid for the current document, whereas the settings with Setup Assistant are the default for all documents and remain in effect until you change them with Setup Assistant.

1. Click Accessibility > Setup Assistant.
2. In the Accessibility Setup Assistant dialog box, choose options that you need or are suitable for your assistive software/hardware.
3. If you click Cancel in any step, all the options you have chosen will be discarded and the original setting will be used.

Tip: You can set more accessibility preferences from File > Preferences > Accessibility/Reading/F

Appropriate nesting

The check reports whether headings are nested properly. If the check fails, do the following steps:

• Right-click the failed element in Headings in the Accessibility Check panel and choose Show in Tags Panel from the context menu. 
• Create elements, change the types of elements, or reorganize the existing elements by dragging them to the proper position.

List items

The rule check reports whether the list structure in the document is correct. Lists must have the following structure: A list element must contain list item elements; a list item element may have a label element (optional) and a list item body element (required). To fix the issue, do the following steps:

For the table structure, which can be complex, Foxit PDF Editor recommends that users check them for accessibility manually.

Rows

If the check fails, open the Tags panel, and make sure that each Table Row in a table is a child of Table, THead, TBody, or TFoot in Foxit PDF Editor Pro. 

TH and TD

For accessibility, Table Header <TH> and Table Data <TD> are children of Table Row <TR>. If the check fails, verify it in the Tags panel in Foxit PDF Editor Pro.

Figures alternate text

For accessibility, images in the document either have alternate text, or are marked as artifacts. If the rule check fails, do any of the following in Foxit PDF Editor Pro:

Tagged form fields

The rule check reports whether all form fields in the document are tagged. If the rule check passes, you can also use the Tooltip in a form field’s properties to provide users with more information.

If it fails, do either of the following to fix the issue in Foxit PDF Editor Pro.

Tagged content

The rule check reports whether all content in the document is tagged or marked as an artifact. 

Artifacts are graphics objects that are typically not part of the author’s original content but rather are generated by the PDF producer application in the course of pagination, layout, or other strictly mechanical processes. Artifacts are not read by a screen reader. Page numbers, headers, and footers are often tagged as artifacts. 

To fix the issue, do any of the following in Foxit PDF Editor Pro:

Accessibility permission flag

Some documents may be protected by the document authors and no content can be copied, printed, extracted, annotated, or edited. This permission setting could interfere with a screen reader’s ability to read the documents because screen readers need to copy or extract the documents’ text to convert it to speech.
